Documentation

data LCIClient #

A very simple chain index client, which only maintains a datum hashes.

withLCIClient #

Arguments

∷ LocalNodeConnectInfo CardanoMode
→ [ChainPoint]	resume points
→ (LCIClient → IO r)
→ IO r

Arguments

∷ LocalNodeConnectInfo CardanoMode
→ [ChainPoint]	resume points
→ IO LCIClient

Create new LCIClient.

Use withLCIClient if possible.

closeLCIClient ∷ LCIClient → IO () #

Close (destroy) LCIClient.

lciWaitUntilSlot ∷ LCIClient → GYSlot → IO GYSlot #

Wait until LCIClient has processed a given slot.

lciLookupDatum ∷ LCIClient → GYLookupDatum #

lciGetCurrentSlot ∷ LCIClient → IO GYSlot #

This is not good gyGetCurrentSlot provider as it might lag plenty behind the current slot of local node.

lciStats ∷ LCIClient → IO (GYSlot, Int) #

Return statistics of LCIClient: currently processed slot and number of hashes known.
